Abstract
About a dozen professors and an unknown number of students at Belgrade University have been affected by a new political purge directed mainly at the faculties of Law and Philosophy. This has evoked widespread concern among professional colleagues abroad and fears for Yugoslavia's previous policy of allowing a wide measure of intellectual and academic freedom to its writers, scholars and creative artists. We reprint below the slightly shortened texts of two memoranda on the subject, followed by the text of an open letter recently sent to President Tito by members of the Eastern Division of the American Philosophical Association. Since the eight philosophers at the centre of the crisis in Belgrade are well-known abroad, it was hoped that expressions of concern from colleagues might alert the Yugoslav authorities to the grave harm they were causing to intellectual freedom in their country.
